Date Jan. 12, 1989.An adapter for a multiple operating mode monitor automatically controls the horizontal and vertical deflection circuits of the monitor cathode ray tube depending upon the characteristics of the video source to which the monitor is connected. The adapter has a digital memory for storing sets of monitor operating parameters for each of a plurality of predetermined operating modes at selectively addressable locations. A processor evaluates horizontal and vertical synchronizing signals from a video source to which the monitor is connected to identify one of the plurality of predetermined operating modes corresponding to the synchronizing signals. The operating mode may be evaluated and identified by measuring the period of the horizontal and vertical synchronizing signals form the video source. The memory location corresponding to the identified mode of operation is selectively addressed, the selected set of operating parameters, which may be in parallel format, being available as an output to a plurality of dynamic digital to analog converters. The digital to analog converters, which may be synchronized with the vertical frequency, provide analog control signals for the horizontal and vertical deflection circuits. The horizontal and vertical deflection circuits are adjusted responsive to the analog control signals to correspond to the selected set of operating parameters. The operating parameters may include horizontal and vertical frequency, horizontal and vertical amplitude, horizontal and vertical deflection phase position, brightness and contrast.

Granted: 1994-04-26
Abstract: ABSTRACT           COMMUNICATION SWITCHING ELEMENT AND METHOD FOR TRANSMITTING VARIABLE LENGTH CELLS The switching element is used for transferring, between X inputs (Il- IX) and Y outputs (Ol- OY), cells divided into subcells of which only the first contains information about the destination output(s) of the cell. This switching element includes:  - a buffer memory (BM) with a plurality (C) of memory locations each having an address (K); and - a memory management means (BMMU) for providing (FMLMC) addresses of free memory locations for storing the subcells therein, and for storing (BQl- BQY, SLM), under the form of linked lists, the memory location addresses used by the subcells, each list being associated to a distinct cell.    The method is adapted to process variable length cells divided into subcells each containing a header (SCH) to distinguish a first/ last subcell (FSC/ LSC) of a cell from other subcells (ISC, LSC).  Use is made of a subcell logic (SL) to detect the succession in either order of a subcell pertaining to a cell and of either a first/ last subcell (FSC/ LSC) of another cell or an idle subcell so as to identify the last/ first subcell (LSC/ FSC) of a cell.

Granted: 1998-04-21
Abstract: A data processing system and method of operation which substantially reduces the time lost in unnecessarily checking for the presence of all memory references required by a special section of code in an operating system before the program is run and which dynamically protect the program requiring the memory reference from crashing if the memory reference is not presently available.  The method assumes that all memory references are available and begins running the special section of code.  If a request is made for information not in assigned memory storage, the data processing system interrupts the running of the special section of code and undoes everything the special section of code has done prior to the interrupt.  The requested memory reference is then located in storage.  The information is retrieved and written into assigned memory.  The special section of code is then restarted and supplied the needed information.   It has been found that it takes much less time to assume the memory references will succeed and occasionally interrupt, erase and restart, than to make a time-consuming preliminary check for all memory references.

Title: Hydraulically operated dockboard
Inventor: HAGEMAN MARTIN P
IPC: B66F7/22
Filed: 1991-01-15
Granted: 1999-07-13
Abstract: A hydraulically operated dockboard including a ramp which is hinged at its rear edge to the frame of the dockboard, and a lip is hinged to the forward edge of the ramp and can be pivoted between a downwardly hanging pendant position and an extended position.  A main hydraulic cylinder unit interconnects the frame and the ramp and by operating the cylinder unit the ramp can be pivoted upwardly from a horizontal cross traffic position to an upwardly inclined position.  A lip cylinder unit interconnects the ramp and the lip, and operation of the lip cylinder unit will pivot the lip from the pendant to an extended position.  The hydraulic system is constructed so that fluid is initially supplied to the main cylinder unit by a pump to raise the ramp, and when the main cylinder unit is fully extended, the increased pressure will shift a valve to supply fluid to the lip cylinder unit.  The valve is constructed so that the valve will be maintained in the shifted position by substantially less pressure than that required to initially shift the valve.  When operation of the pump is discontinued, the ramp will descend and the back pressure generated by the weight of the lip acting against the valve will retain the valve in the shifted position to maintain the lip in the extended condition until the lip engages the bed of a truck.                :
